Hi, recently we tried to enable MSI interrupts with nouveau. Unfortunately there have been some reports of things failing with certain cards, where it isn't entirely clear if this is a GPU errata or some other component in the PCIe chain failing. Could you perhaps investigate if there are any known Nvidia GPU erratas with regard to MSI interrupts, or maybe tell us the generations of cards

Hello, I am in the process of "trying out" Puppet, and so far, it is going really well, and I can see a clear line of how we can use it internally. I do have one question though with regard to the using the onlyif parameter of the exec command (as per here http://docs.puppetlabs.com/references/latest/type.html#exec). Ideally, what I would like to do is to only run a PowerShell exec
